Door-window sensor

Abstract

This invention discloses a door-window sensor which can be integrated with the associated fittings of the door and window. The sensor cannot be seen from appearance of the door and window, thus making the door and window beautiful and elegant on the whole. It can be installed easily without the limitation of door and window in the external dimension; it is used to determine whether the door and window is locked or closed; its cost is at a lower level. For the sensor, the door and window consists of frame and leaf. The leaf is driven by the motor to rotate around the connected axis and locked to the frame by means of lock. It gets close to inner side of the frame when closed and away from inner side of the frame when opened. The sensor consists of induction generating components, inductive device and data processing unit. One of the induction generating component and inductive device is arranged on the outside of leaf corresponding to the lock and the other is arranged inside the frame corresponding to the lock hole. The data processing unit is arranged outside or inside the door and window. State change of the inductive device is sent to the data processing unit by wired and/or wireless means.
